traffic_server

Description

Options

-n COUNT, --net_threads COUNT

-U COUNT, --udp_threads COUNT

-a, --accepts_thread

-b, --accept_till_done

-p PORT, --httpport PORT

-f, --disable_freelist

In order to improve performance, traffic_server caches commonly used data structures in a set of free object lists. This option disables these caches, causing traffic_server to use malloc(3) for every allocation. Though this option should not commonly be needed, it may be beneficial in memory-constrained environments or where the working set is highly variable.

-F, --disable_pfreelist

Disable free list in ProxyAllocator which were left out by the -f option. Please note that this option is a temporary, testing option, and will be removed in the future.

-o LEVEL, --dprintf_level LEVEL

-R LEVEL, --regression LEVEL

-r TEST, --regression_test TEST

-l, --regression_list

If Traffic Server was built with tests enabled, this option lists the available tests.

-T TAGS, --debug_tags TAGS

-B TAGS, --action_tags TAGS

-i COUNT, --interval COUNT

-M, --remote_management

-C CMD, --command CMD

-k, --clear_hostdb

-K, --clear_cache

-c CORE, --read_core CORE

--accept_mss MSS

-t MSECS, --poll_timeout MSECS

-h, --help

Print usage information and exit.

-V, --version

Print version information and exit.

Environment

PROXY_REMOTE_MGMT

This environment variable forces traffic_server to believe that it is being managed by traffic_manager.

PROXY_AUTO_EXIT

When this environment variable is set to an integral number of seconds, traffic_server will exit that many seconds after startup. This is primarily useful for testing.

Signals

SIGINT, SIGTERM

On SIGINT and SIGTERM, traffic_server exits.

SIGUSR1

On SIGUSR1, traffic_server logs its current memory usage.

SIGUSR2

On SIGUSR2, traffic_server re-opens its standard error and standard out file descriptors.
